Thermal efficiency is the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
The formula to calculate the thermal efficiency of an Otto cycle engine is: Thermal Efficiency 1 - (1 / compression ratio)
Mechanical efficiency is determined by dividing the output work by the input work, while thermal efficiency is calculated by dividing the useful work output by the heat input. Relative efficiency is the ratio of mechanical efficiency to thermal efficiency and can be used to compare the effectiveness of a machine in converting input energy to useful work.
Factors of thermal efficiency include combustion efficiency, heat transfer efficiency, and frictional losses. Combustion efficiency refers to how well fuel is converted into heat energy, while heat transfer efficiency measures how effectively heat is transferred within the system. Frictional losses occur due to resistance in moving parts and can reduce overall energy output. Improving combustion efficiency, enhancing heat transfer mechanisms, and minimizing frictional losses can all help increase thermal efficiency.
To find thermal efficiency in a system, you can use the formula: Thermal Efficiency (Useful Energy Output / Energy Input) x 100. This calculation involves determining the amount of useful energy produced by the system compared to the total energy input. The higher the thermal efficiency percentage, the more effectively the system converts energy into useful work.
A good boiler typically has a thermal efficiency of around 85% to 95%. This means that it can convert 85% to 95% of the energy in its fuel into usable heat for heating water or spaces. Higher efficiency boilers are more cost-effective and environmentally friendly.

It is not a good efficiency engine.
In saying what the overall efficiency would be, I suppose you mean for other processes, creating the chemical energy for example, and using the thermal energy. This is impossible to answer, not knowing what these processes are.
compare the two stroke and four stroke engine in power output and thermal efficiency?
It is not a good efficiency engine.
